Requirements for installation of Self-Hosted Custom Edition (Kubernetes or Red Hat OpenShift Container Platform)

Before you install Self-Hosted Custom Edition (Kubernetes or Red Hat OpenShift Container Platform), ensure that you meet all the requirements.

For more information about installing Self-Hosted Custom Edition (Kubernetes or Red Hat OpenShift Container Platform), see Instana self-hosted deployment.

Supported Kubernetes and Red Hat® OpenShift® versions

The Kubernetes operator runs on any basic Kubernetes distribution and Red Hat OpenShift.

Installation of Self-Hosted Custom Edition on Linux on Power (ppc64le) is supported only on Red Hat OpenShift.

Table 1. Supported versions
Platform Minimum supported version
Kubernetes 1.22
Red Hat OpenShift 4.13 (Linux® x86_64)
4.13 (Linux® on IBM Z® and LinuxONE)
4.13 (Linux® on Power® (ppc64le))

System requirements for Self-Hosted Custom Edition on Linux on Power (ppc64le)

The following requirements are for installing Self-Hosted Custom Edition on Red Hat OpenShift on Linux on Power (ppc64le):

  • Master nodes with a supported OpenShift Container Platform version. See Table 1. Supported versions.
  • Block storage for Instana server and data store components. For more information, see Storage considerations.
  • A bastion node for accessing OpenShift Container Platform cluster control plane.
  • At least 5 worker nodes with 2 vCPUs and 64 GB memory each. For CPU requirement, you can use either a dedicated CPU or an uncapped shared CPU.
    • If you're using a dedicated CPU, each worker node must have at least 2 physical cores with SMT8 enabled.
    • If you're using a shared CPU, each worker node must have at least 2 virtual cores with SMT8 enabled and with an entitled capacity 1. This capacity ensures 16 CPU threads per worker node.
      • To verify the capacity on the worker node, run the following command:
        lscpu
      • To verify the CPU configuration on the worker node, run the following command:
        lparstat -i
